Silver fiber; coverage: The surface is fully covered with silver fiber, and the finger sleeve offers high sensitivity across the entire surface. It accurately responds to every touch, swipe, and click without error, enhancing precision during use. Hand-sewn: This finger sleeve is crafted by hand-sewing sterling silver fiber fabric. Slight variations in appearance may occur between individual pieces. There may be a small imperfection directly above the nail area, but it does not impact functionality. The handmade construction ensures a snug and comfortable fit. Feels like bare fingers: The silver fiber material is ultra-thin and highly sensitive, with a coefficient of friction similar to that of bare fingers on a screen. It provides reliable grip without being overly slippery, unlike textile-based alternatives. Silver fiber fabric: Finger sleeves made from silver fiber fabric offer a cooler and more comfortable experience compared to rubber or cotton options. Due to the ultra-thin design, they remain breathable and comfortable even in warm conditions. Note ultra-thin design: Excessive moisture may affect performance, so this product may not be ideal for individuals with excessive sweating. Elasticity is limited compared to textile sleeves. For thicker fingers, a textile option may provide a better fit. The surface contains silver ions that may darken over time due to natural oxidation with prolonged use.
